Terms of Use

Plain-language terms. Using the site means you accept them.

The calculators are estimates

Every result on this site is computed from the numbers you enter and, where noted, from typical reference values (spool weights, hotend limits, printer power draw, marketplace fees). They are provided to help you plan and are not guaranteed to be correct for your equipment, materials or market. Check anything that matters — a price you'll charge, a firmware value you'll save, a part that must fit — before relying on it.

Generated G-code

The test tower generator produces G-code from the settings you provide. It cannot know your printer's physical limits, start-up requirements, Z offset or safety features. You are responsible for previewing the file and for anything that happens when it runs. Never leave a printer running an unfamiliar file unattended.

No warranty

The site and everything on it are provided "as is", without warranty of any kind. To the fullest extent allowed by law, we are not liable for any loss or damage — including failed prints, damaged equipment, lost revenue or mispriced work — arising from use of the site.

Using the content

You're welcome to link to any page, quote the formulas, and use the calculators for personal or commercial purposes. Please don't copy whole pages or present the calculators as your own; if you'd like to embed or reuse something, ask.

Third-party links

Links to other sites are provided for convenience. We don't control their content and aren't responsible for it.

Changes

These terms may be updated; the date at the top reflects the latest revision. Continued use after a change means you accept it.
